you are wrong it has to do with the lack of resources. Please go to control panel device manager and under the viewing option select show hidden objects, a good change you will see your external graphics there. look for it and when you don't see it select view on connection. Somewhere under the pci express downport big change you will find your hidden graphics card.

maybe you misunderstood me? My issue is no really dsdt related, because my setup works perfectly fine without that. My only thing is, that my bootop procedure is way too long, and the dsdt is relating to if it would fasten up the things? Because how I bootup is: uninstall all drivers, reboot to windows, install drivers back after hotplugging egpu, shutdown, boot to macos, hotplug egpu, automate script first normal mode, then -a mode, shutdown, and booting back to windows, plugging in the egpu when the spinning wheel starts- what I want to do is to skip somehow the driver uninstallation process all the time, and I'm not sure why, but that's my only way booting succesfully?

Well could really be a ressources probleem tough. Why dont you try to do the dsdt method and see what happens? Could very Well fix your slow bootup issues. Thank you for clarifiying

This has nothing to do with DSDT. The system freeze occurs during the POST stage. Switching to an AMD card might help.

Have you tried both TB ports and hot-plugging, then disabling/re-enabling the parent downstream switch port in device manager?

No, not yet. 

Today will be exciting anyways, as with the pascal drivers release for macOS, I'll play around with that, too. And I'll try to experiment with what you said, @goalque. Will report back later!

I have an early 2015 13" rMBP with a GTX 1050ti and Akitio Thunder2. It is a total pain getting into bootcamp with the eGPU connected. I really just have to try 2-5 times and hope it works, what I don't understand is why it is so inconsistent. Sometimes it works after booting up first time with the eGPU is plugged in, often I get it working when I plug it in as soon as the windows logo appeared, and once I was actually able to hot plug the eGPU after startup and it worked perfectly!

Most of the time windows hangs on the boot screen and sometimes the screen will just stay completely black on startup. I rarely run into error 12 or whatever the other one is, most of the time if I can get the computer started up with the eGPU connected it will work properly. I have tried all the suggestions on this thread but the most reliable for me is plugging in the eGPU as soon as the windows logo shows up (but before the loading thing does) or just starting up from scratch with the eGPU connected (I usually alternate between them). Right now I love the simple setup and this is really the only problem with it. If someone could find an easy, reliable solution to this that would be awesome.

@Froast I also have a system setup like you. And the same mistakes. But that is when I use windows 10. When I downgrade to windows 8.1 it works very well. There are not any errors. People say booting up with windows 10 is a real challenge. Currently I am satisfied with windows 8.1. Hopefully there is a way that works perfectly for Windows 10. Smile

I never got my Thunder3 and 970 card to work over TB3-to-tb adapter under 10.11.

I upgraded to 10.12 and reinstalled everything by the book and still can't get it going.

The Thunder3 is now supported, the nvidia drivers are the latest and the system profiler can see tha card but still only identifies it as kind of generic strange card. Can i get it going or might it be a dead card?

Poorly fitted connector was the culprit. Grin

I'm having the same problem. It works on the windows side. 

I've un installed the nvidia device manager, re-installed it, scrip sees GTX1060. If I hotplug the thunder 2 the system report only sees Chip Model. 

I get caught in the endless boot loop when trying to restart. Haven't seen a solution so far that helps this. 

Anyone have any thoughts on what to try next?
